TECHNICAL FIELD

The present invention relates to 8-azaprostaglandins.

More specifically, the present invention relates to:

-   (1) an 8-azaprostaglandin derivative compound represented by formula     (I):

(wherein all symbols have the same meanings as described below), a pharmaceutically acceptable salt thereof or a cyclodextrin clathrate thereof,

-   (2) a process for the preparation thereof, and -   (3) a pharmaceutical composition comprising thereof as an active     ingredient.

BACKGROUND ART

Prostaglandin E₂ (abbreviated as PGE₂) has been known as a metabolite in the arachidonate cascade. It has been known that PGE₂ possesses cyto-protective activity, uterine contractive activity, a pain-inducing effect, a promoting effect on digestive peristalsis, an awakening effect, a suppressive effect on gastric acid secretion, hypotensive activity and diuretic activity and so on.

A recent study has proved existence of various PGE subtype receptors possessing a different physical role from each other. At present, four receptor subtypes are known and they are called EP₁, EP₂, EP₃, and EP₄ (Negishi M., et al., J. Lipid Mediators Cell Signaling, 12, 379-391 (1995)).

It is thought that EP₂ subtype receptor relates to inhibition of producing TNF-α and acceleration of producing IL-10. Therefore, the compounds which can bind on EP₂ subtype receptor are expected to be useful for the prevention and/or treatment of immune diseases (e.g., autoimmune diseases such as amyotrophic lateral sclerosis (ALS), multiple sclerosis, Sjogren's syndrome, rheumatoid arthritis and systemic lupus erythematosus etc., and rejection after organ transplantation), allergic diseases (e.g., asthma, allergic rhinitis, allergic conjunctivitis, atopic dermatitis, food allergy), neuronal cell death, dysmenorrhea, premature birth, abortion, baldness, retinal neuropathy such as glaucoma, erectile dysfunction, arthritis, pulmonary injury, pulmonary fibrosis, pulmonary emphysema, bronchitis, chronic obstructive pulmonary disease, hepatic injury, acute hepatitis, liver cirrhosis, shock, nephritis (acute nephritis, chronic nephritis), renal failure, circulatory diseases (e.g., hypertension, myocardial ischemia, chronic arterial obstruction, vibration disease), systemic inflammatory response syndrome, sepsis, hemophagocytosis syndrome, macrophage activation syndrome, still disease, Kawasaki Disease, burn, systemic granuloma, ulcerative colitis, Crohn disease, hypercytokinemia at dialysis, multiple organ failure, and bone diseases (e.g., fracture, refracture, intractable fracture, nonunion, pseudarthrosis, osteomalacia, Paget's disease of bone, ankylosing spondylitis, bone metastasis, osteroarthritis and destruction of bone/cartilage due to these analogous diseases) etc. It is also considered that the compounds are useful as an agent for accelerating the osteogenesis/cure after bone surgery (e.g., fracture, bone graft, artificial arthrogenesis, spinal fusion, surgery for multiple myeloma, lung cancer, breast cancer, etc., other bone repair) or substitute treatment for bone grafting. It is further considered that the compounds are useful agents for accelerating the regeneration of peridontium in periodontal disease etc.

Processes for the Preparation of the compound of the present invention:

The compound represented by formula (I) can be prepared by the following method or the method described in Example.

-   1. Among the compounds represented by formula (I), a compound in     which T represents oxygen atom, and X represents —CH₂—, i.e., a     compound represented by formula (IA):

(wherein all symbols have the same meanings as described above.) can be prepared by the following method.

The compound represented by formula (IA) can be prepared by reductive amination of the compounds of formula (II):

(wherein R¹⁸ is C1-10 alkyl and E′ has the same meaning as E. With the proviso that, hydroxyl, amino, carboxy or formyl in the group represented by E′ may be protected, if necessary.) and a compound represented by formula (III):

(wherein A′ and D′ have the same meanings as A and D, respectively. With the proviso that, hydroxyl, amino, carboxy or formyl in the group represented by A′ and D′ may be protected, if necessary.), if necessary, followed by removal of the protective group from the resulting product.

The reductive amination is well known. For example, it may be carried out in an organic solvent (e.g., methanol, ethanol, dichloromethane, tetrahydrofuran, dimethoxyethane, diethyl ether) in the presence of reducing agent (e.g., sodium cyanoborohydride, sodium borohydride, sodium triacetoxyborohydride, pyridine borane) at 0 to 100° C.

The removal of the protective group may be carried out by following method.

The reaction for removing the protective group for carboxy, hydroxy, amino or formyl is well known, including, for example, the following:

-   (1) alkali hydrolysis, -   (2) deprotection under acidic condition, -   (3) deprotection through hydrogenolysis, -   (4) silyl deprotection, -   (5) deprotection with metal, -   (6) deprotection with organic metal.

These methods are described concretely.

-   (1) The deprotection through alkali hydrolysis may be effected, for     example, in an organic solvent (e.g., methanol, tetrahydrofuran,     dioxane) by the use of an alkali metal hydroxide (e.g., sodium     hydroxide, potassium hydroxide, lithium hydroxide), an alkaline     earth metal hydroxide (e.g., barium hydroxide, calcium hydroxide) or     a carbonate (e.g., sodium carbonate, potassium carbonate), or an     aqueous solution thereof or their mixture, at 0 to 40° C. -   (2) The deprotection under acidic condition may be effected, for     example, in an organic solvent (e.g., dichloromethane, chloroform,     dioxane, ethyl acetate, anisole) with an organic acid (e.g., acetic     acid, trifluoroacetic acid, methanesulfonic acid, p-toluenesulfonic     acid) or an inorganic acid (e.g., hydrochloric acid, sulfuric acid)     or their mixture (hydrogen bromide/acetic acid), at 0 to 100° C. -   (3) The deprotection through hydrogenolysis may be effected, for     example, in a solvent (e.g., ether-type (e.g., tetrahydrofuran,     dioxane, dimethoxyethane, diethyl ether), alcohol-type (e.g.,     methanol, ethanol), benzene-type (e.g., benzene, toluene),     ketone-type (e.g., acetone, methyl ethyl ketone), nitrile-type     (e.g., acetonitrile), amide-type (e.g., dimethylformamide), water,     ethyl acetate, acetic acid, or mixed solvent of two or more of     these), in the presence of a catalyst (e.g., palladium-carbon,     palladium-black, palladium hydroxide, platinum oxide, Raney nickel),     in a hydrogen atmosphere under a normal pressure or increased     pressure or in the presence of ammonium formate, at 0 to 200° C. -   (4) The silyl deprotection may be effected, for example, in a     water-miscible organic solvent (e.g., tetrahydrofuran, acetonitrile)     by the use of tetrabutylammonium fluoride, at 0 to 40° C. -   (5) The deprotection with metal may be effected, for example, in an     acidic solvent (acetic acid, buffer having pH 4.2 to 7.2, or mixture     of their solution with organic solvent such as tetrahydrofuran) in     the presence of zinc powder with or without ultrasonic waves applied     thereto, at 0 to 40° C. -   (6) The deprotection with metal complex may be effected, for     example, in an organic solvent (e.g., dichloromethane,     dimethylformamide, tetrahydrofuran, ethyl acetate, acetonitrile,     dioxane, ethanol), water or their mixed solvent, in the presence of     a trapping reagent (e.g., tributyltin hydride, triethylsilane,     dimedone, morpholine, diethylamine, pyrrolidine), an organic acid     (e.g., acetic acid, formic acid, 2-ethylhexanoic acid) and/or an     organic acid salt (e.g., sodium 2-ethylhexanoate, potassium     2-ethylhexanoate), in the presence or absence of a phosphine-type     reagent (e.g., triphenyl phosphine), by the use of a metal complex     (tetrakistriphenylphosphine palladium(0),     dichlorobis(triphenylphosphine) palladium(II), palladium(II)     acetate, chlorotris(triphenylphosphine) rhodium(I)), at 0 to 40° C.

Apart from the above, the deprotection may also be effected, for example, according to the methods described in T. W. Greene, Protective Groups in Organic Synthesis, Wiley, N.Y., 1999.

The intended compounds of the invention may be readily produced through selective use of the deprotecting reaction, which could be readily understood by anyone skilled in the art.

The carboxyl-protective group includes, for example, methyl, ethyl, allyl, t-butyl, trichloroethyl, benzyl (Bn), and phenacyl etc.

The hydroxyl-protective group includes, for example, methyl, trityl, methoxymethyl (MOM), 1-ethoxyethyl (EE), methoxyethoxymethyl (MEM), 2-tetrahydropyranyl (THP), trimethylsilyl (TMS), triethylsilyl (TES), t-butyldimethylsilyl (TBDMS), t-butyldiphenylsilyl (TBDPS), acetyl (Ac), pivaloyl, benzoyl, benzyl (Bn), p-methoxybenzyl, allyloxycarbonyl (Alloc), and 2,2,2-trichloroethoxycarbonyl (Troc) etc.

The amino-protective group includes, for example, benzyloxycarbonyl, t-butoxycarbonyl, allyloxycarbonyl (Alloc), 1-methyl-1-(4-biphenyl)ethoxycarbonyl (Bpoc), trifluoroacetyl, 9-fluorenylmethoxycarbonyl, benzyl (Bn), p-methoxybenzyl, benzyloxymethyl (BOM), and 2-(trimethylsilyl)ethoxymethyl (SEM) etc.

The formyl-protective group is, for example, acetal (e.g., dimethylacetal) etc.

The carboxy, hydroxy, amino or formyl-protective may be any others than those mentioned above, capable of being readily and selectively removed, and are not specifically defined. For example, those described in T. W. Greene, Protective Groups in Organic Synthesis, 3rd Ed., Wiley, N.Y., 1999 may be used.

(wherein A^(a) is A^(1a) or A^(2a), A^(1a) is 1) C1-7 straight-chain alkylene optionally substituted by 1 to 2 C1-4 alkyl(s), 2) C2-7 straight-chain alkenylene optionally substituted by 1 to 2 C1-4 alkyl(s), or 3) C2-7 straight-chain alkynylene optionally substituted by 1 to 2 C1-4 alkyl(s), A^(2a) is -G^(1a)-G^(2a)-G³-, G^(1a) is 1) C1-3 alkylene optionally substituted by 1 to 2 C1-4 alkyl(s), 2) C2-3 alkenylene optionally substituted by 1 to 2 C1-4 alkyl(s), or 3) C2-3 alkynylene optionally substituted by 1 to 2 C1-4 alkyl(s), G^(2a) has the same meaning as G². With the proviso that, hydroxyl, amino, carboxy or formyl in the group represented by G^(2a) may be protected, if necessary. Other symbols have the same meanings as defined above.), if necessary, followed by removal of the protective group from the resulting product.

The reductive amination and the removal of the protective group may be carried out by the above method.

-   3. Among the compounds represented by formula (I), a compound in     which T represents oxygen atom, and X represents —O—, i.e., a     compound represented by formula (IB):

(wherein all symbols have the same meanings as described above.) can be prepared by the following method.

The compounds represented by formula (IB) can be prepared by cyclization of the compounds of formula (VI):

(wherein all symbols have the same meanings as defined above.), if necessary, followed by removal of the protective group from the resulting product.

The cyclization is well known. For example, it may be carried out in an organic solvent (e.g., tetrahydrofuran, dichloromethane, dimethoxyethane, diethyl ether, dimethylformamide) in the presence of a base (e.g., triethylamine, pyridine, potassium carbonate, sodium bicarbonate) with carbonylation agent (e.g., triphosgene, 1,1′-carbonyldiimidazole (CDI), phosgene) at 0 to 50° C.

The removal of the protective group may be carried out by the above method.

-   4. Among the compounds represented by formula (I), a compound in     which T represents oxygen atom, and X represents —S—, i.e., a     compound represented by formula (IC):

The compounds represented by formula (ID) can be prepared by thioamidation of the compounds of formula (VIII):

(wherein all symbols have the same meanings as defined above.), if necessary, followed by removal of the protective group from the resulting product.

The thioamidation is well known. For example, it may be carried out in an organic solvent (e.g., toluene, diethyl ether, methylene chloride, chloroform, dioxane, tetrahydrofuran) in the presence of a thyonation agent (e.g., Lawesson's Reagent (2,4-bis(4-methoxyphenyl)-1,3-dithia-2,4-diphosphetane-2,4-disulfide), phosphorus pentoxide) at 0 to 150° C.

The removal of the protective group may be carried out by the above method.

-   6. Among the compounds represented by formula (I), a compound in     which D represents —CH₂OH, i.e., a compound represented by formula     (IE):

The compounds represented by formula (IE) can be prepared by reduction of the compounds of formula (IX):

(wherein all symbols have the same meanings as defined above.), if necessary, followed by removal of the protective group from the resulting product.

The reduction is well known. For example, it may be carried out in an organic solvent (e.g., tetrahydrofuran, dimethoxyethane, diethyl ether, dimethylformamide, dioxane, methanol, ethanol, isopropanol) or an aqueous solution thereof in the presence of a reducing agent (e.g., sodium borohydride, lithium borohydride) at 0 to 70° C.

With the proviso that, amino, hydroxy or carboxy in the compounds represented by formula (XI-4) may be protected, if necessary.), if necessary, followed by removal of the protective group from the resulting product.

The method of amidation is known. For example, it includes the method

-   (1) via an acyl halide, -   (2) via a mixed acid anhydride, -   (3) using a condensing agent.

These methods are explained as follows.

-   (1) The method via an acyl halide may be carried out, for example,     by reacting carboxylic acid with an acyl halide (e.g., oxalyl     chloride or thionyl chloride etc.) in an organic solvent (e.g.,     chloroform, dichloromethane, diethyl ether or tetrahydrofuran) or     without a solvent at −20° C. to reflux temperature. And then the     obtained acyl halide derivative may be reacted with amine in an     inert organic solvent (e.g., chloroform, dichloromethane, diethyl     ether or tetrahydrofuran) in the presence of a base (e.g., pyridine,     triethylamine, dimethylaniline, dimethylaminopyridine or     diisopropylethylamine etc.) at 0 to 40° C. As an alternative, the     obtained acyl halide derivative may be reacted in an organic solvent     (e.g., dioxane, tetrahydrofuran) using an alkaline aqueous solution     (e.g., sodium bicarbonate, sodium hydroxide) at 0 to 40° C. -   (2) The method via a mixed acid anhydride may be carried out, for     example, by reacting carboxylic acid with an acyl halide (e.g.,     pivaloyl chloride, tosyl chloride or mesyl chloride) or an acid     derivative (e.g., ethyl chloroformate or isobutyl chloroformate) in     an organic solvent (e.g., chloroform, dichloromethane, diethyl     ether, tetrahydrofuran) or without a solvent, in the presence of a     base (e.g., pyridine, triethylamine, dimethylaniline,     dimethylaminopyridine or diisopropylethylamine) at 0 to 40° C. And     then the obtained mixed acid anhydride derivative may be reacted     with amine in an organic solvent (e.g., chloroform, methylene     chloride, diethyl ether or tetrahydrofuran), at 0 to 40° C. -   (3) The method using a condensing agent may be carried out, for     example, by reacting carboxylic acid with amine in an organic     solvent (e.g., chloroform, dichloromethane, dimethylformamide,     diethyl ether or tetrahydrofuran) or without a solvent, in the     presence or absence of a base (e.g., pyridine, triethylamine,     dimethylaniline or dimethylaminopyridine), using a condensing agent     (e.g., 1,3-dicyclohexyl carbodiimide (DCC),     1-ethyl-3-[3-(dimethylamino)propyl]carbodiimide (EDC),     1,1′-carbodiimidazole (CDI), 2-chloro-1-methylpyridinium iodide, or     1-propanephosphonic acid cyclic anhydride (PPA)), in the presence or     absence of 1-hydroxybenzothiazole (HOBt), at 0 to 40° C.

The reaction described in (1), (2) and (3) may be carried out under an inert gas (e.g., argon, nitrogen) to avoid water in order to obtain a preferable result.

The removal of the protective group may be carried out by the above method.

-   8. Among the compounds of the present invention represented by     formula (I), a compound in which D represents —O—(CO-amino acid     residue-NH)_(m)—H or —OCO—R¹⁰, i.e., a compound represented by     formula (IG):

These methods are explained as follows.

-   (1) The method via an acyl halide may be carried out, for example,     by reacting carboxylic acid with an acid-halogenating agent (e.g.,     oxalyl chloride or thionyl chloride etc.) in an organic solvent     (e.g., chloroform, dichloromethane, diethyl ether or     tetrahydrofuran) or without a solvent at −20° C. to reflux     temperature. And then the obtained acyl halide derivative may be     reacted with alcohol in an inert organic solvent (e.g., chloroform,     methylene chloride, diethyl ether or tetrahydrofuran) in the     presence of a base (e.g., pyridine, triethylamine, dimethylaniline,     dimethylaminopyridine or diisopropylethylamine etc.) at 0 to 40° C.     As an alternative, the obtained acyl halide derivative may be     reacted in an organic solvent (e.g., dioxane, tetrahydrofuran) using     an alkaline aqueous solution (e.g., sodium bicarbonate, sodium     hydroxide) at 0 to 40° C. -   (2) The method via a mixed acid anhydride may be carried out, for     example, by reacting carboxylic acid with an acyl halide (e.g.,     pivaloyl chloride, tosyl chloride or mesyl chloride) or an acid     derivative (ethyl chloroformate or isobutyl chloroformate) in an     organic solvent (e.g., chloroform, dichloromethane, diethyl ether,     tetrahydrofuran) or without a solvent, in the presence of a base     (e.g., pyridine, triethylamine, dimethylaniline,     dimethylaminopyridine or diisopropylethylamine) at 0 to 40° C. And     then the obtained mixed acid anhydride derivative may be reacted     with alcohol in an organic solvent (e.g., chloroform,     dichloromethane, diethyl ether or tetrahydrofuran), at 0 to 40° C. -   (3) The method using a condensing agent may be carried out, for     example, by reacting carboxylic acid with alcohol in an organic     solvent (e.g., chloroform, dichloromethane, dimethylformamide,     diethyl ether or tetrahydrofuran) or without a solvent, in the     presence or absence of a base (e.g., pyridine, triethylamine,     dimethylaniline or dimethylaminopyridine), using a condensing agent     (e.g., 1,3-dicyclohexyl carbodiimide (DCC),     1-ethyl-3-[3-(dimethylamino)propyl]carbodiimide (EDC),     1,1′-carbodiimidazole (CDI), 2-chloro-1-methylpyridinium iodide,     1-propanephosphonic acid cyclic anhydride (PPA)), in the presence or     absence of 1-hydroxybenzothiazole (HOBt), at 0 to 40° C.

Pharmacological Activity of the Compounds of the Invention:

For example, the pharmacological activities of the compounds of the invention were confirmed in experiments performed in a laboratory using the cells which express prostanoid receptor sub-types.

-   (i) Experiment for receptor-binding using cells which express     prostanoid receptor sub-types

According to the method of Sugimoto et al. (J. Biol. Chem., 267, 6463-6466 (1992)), CHO cells which expressed prostanoid receptor sub-types (murine EP₁, EP₂, EP_(3α), and EP₄, respectively) were prepared and used as membrane authentic samples.

A reaction solution (200 μl) containing the prepared membrane fraction (0.5 mg/ml) and ³H-PGE₂ was incubated at room temperature for 1 hour. The reaction was terminated with ice cold buffer (3 ml), and the reaction mixture was filtered under suction through a glass filter (GF/B), on which the binding ³H-PGE₂ was trapped, and the binding radioactivity was measured by means of a liquid scintillator.

The Kd value was obtained from the Scatchard plots [Ann. N.Y. Acad. Sci., 51, 660 (1949)]. Non-specific binding was obtained as the binding in the presence of an excess amount (2.5 μM) of unlabelled PGE₂. Measurement of the binding inhibition for ³H-PGE₂ with the compounds of the present invention was performed by adding ³H-PGE₂ (2.5 nM) and a series of concentrations of the compound of the present invention. In this reaction, the following buffer was used in all cases.

-   Buffer: 10 mM potassium phosphate (pH 6.0), 1 mM EDTA, 10 mM MgCl₂,     and 0.1M NaCl.

Dissociation constant Ki (μM) of each compound was calculated from the following equation. Ki=IC ₅₀/(1+([C ]/Kd))

-   IC₅₀ The concentration of the compound of the present invention     which inhibits half of the specific binding of [³H]PGE₂ -   C: The concentration of [³H]PGE₂ -   Kd: The dissociation constant of [³H]PGE₂

The binding activity (Ki) of the compound prepared in Example 4(1) to the mouse EP₂ receptor was 14 nM.

The toxicity of the compounds of the present invention represented by formula (I) is very low and therefore the compounds may be considered safe for pharmaceutical use.

These compounds may be used singly or in admixture of two or more thereof. Besides these compounds, poly-α-cyanoacrylic acid esters, poly-β-hydroxybutyric acids, polytrimethyleneoxates, polyorthoesters, polyorthocarbonates, polyethylene carbonates, poly-γ-benzyl-L-glutamic acids and poly-L-alanines may be used singly or in admixture of two or more thereof. Among these compounds, preferred are polylactic acids, polyglycolic acids and lactic acid-glycolic acid copolymers, more preferably lactic acid-glycolic acid copolymers.

The average molecular weight of these in vivo degradable polymers to be used in the present invention is preferably from about 2,000 to 800,000, more preferably from about 5,000 to 200,000. For example, the polylactic acid preferably has a weight-average molecular weight of from about 5,000 to 100,000, more preferably from about 6,000 to 50,000. The polylactic acid can be synthesized according to any known preparation method per se. In the lactic acid-glycolic cid copolymer, the composition ratio of the lactic acid to the glycolic acid is preferably from about 100/0 to 50/50 (w/w), particularly from about 90/10 to 50/50. The weight-average molecular weight of the lactic acid-glycolic acid copolymer is preferably from about 5,000 to 100,000, more preferably from about 10,000 to 80,000. The lactic acid-glycolic acid copolymer can be synthesized according to any known preparation method per se.

The term “weight-average molecular weight” as used herein is meant to indicate molecular weight in polystyrene equivalence determined by gel permeation chromatography (GPC).

The aforementioned in vivo degradable polymer may be changed depending on the intensity of pharmacological activity of the compounds represented by formula (I) and the desired medicines to be released so far as the aforementioned aims of the present invention are accomplished. For example, the in vivo degradable polymer may be used in an amount of from about 0.2 to 10,000 times, preferably from about 1 to 1,000 times, more preferably from about 1 to 100 times (by weight) that of the physiologically active material.

Examples of the process for the preparation of microspheric, microcapsuled and nanospheric preparations include submerged drying method (e.g., o/w method, w/o/w method), phase separation method, spray drying method, granulation method by ulractritical fluid, and methods analogous thereto.

The submerged drying method (o/w method) and spray drying method will be further described hereinafter.

-   (1) In the submerged drying method (o/w method), a solution of an in     vivo degradable polymer in an organic solvent is prepared at first.     The organic solvent to be used in the preparation of the     microspheric, microcapsuled and nanospheric preparations preferably     has a boiling point of 120° C. or less. Examples of the organic     solvent employable herein include halogenated hydrocarbons (e.g.,     dichloromethane, chloroform), aliphatic esters (e.g., ethyl     acetate), ethers, aromatic hydrocarbons, and ketones (e.g.,     acetone). These compounds may be used in admixture of two or more at     a proper ratio. Among these organic solvents, preferred are     dichloromethane and acetonitrile, particularly dichloromethane. The     concentration of the in vivo degradable polymer in the organic     solution depends on the molecular weight of the in vivo degradable     polymer, the kind of the organic solvent, etc. but is normally     predetermined to be from about 0.01 to 80% (v/w), preferably from     about 0.1 to 70% (v/w), more preferably from about 1 to 60% (v/w).

The compound represented by formula (I) is then added to and dissolved in the solution of the in vivo degradable polymer in an organic solvent thus obtained, optionally in combination with other pharmaceutical preparations. The amount of the compound represented by formula (I) to be added optionally in combination with the other pharmaceutical preparations depends on the kind of the pharmaceutical preparations to be added, the action of the pharmaceutical preparations in osteogenesis, the duration of the action, etc. but is normally from about 0.001% to 90% (w/w), preferably from about 0.01% to 80% (w/w), more preferably from about 0.3 to 30% (w/w) as calculated in terms of concentration in the solution of in vivo degradable polymer in an organic solvent.

Subsequently, the organic solution thus prepared is added to an aqueous phase which is then processed by an agitator, emulsifier or the like to form an o/w emulsion. The volume of the aqueous phase during this procedure is predetermined to be from about 1 to 10,000 times, preferably from about 2 to 5,000 times, particularly from about 5 to 2,000 times that of the oil phase. An emulsifier may be added to the aqueous phase which is an external phase. As such an emulsifier there may be normally used any material capable of forming a stable o/w emulsion. Examples of the emulsifier employable herein include anionic surface active agents, nonionic surface active agents, polyoxyethylene castor oil derivatives, polyvinyl pyrrolidone, polyvinyl alcohol, carboxymethyl cellulose, lecitine, and gelatin. These compounds may be used in proper combination. The concentration of the emulsifier in the external aqueous phase is preferably from about 0.001% to 20% (w/w), more preferably from about 0.01% to 10% (w/w), particularly from about 0.05% to 5% (w/w).

The evaporation of the solvent which is an oil phase can be accomplished by any commonly used method. In some detail, the evaporation of the solvent may be effected at ordinary pressure or gradually falling pressure with stirring by an agitator, magnetic stirrer or the like or may be effected while the pressure is being adjusted using a rotary evaporator. The microspheric preparation thus obtained is then fractionated by centrifugal separation or filtration. The microspheric preparation is washed with a surface active agent solution, alcohol or the like several times to remove the free compound represented by formula (I), optionally in combination with other pharmaceutical preparations, and the emulsifier from the surface thereof, again dispersed in distilled water or a dispersant containing a vehicle (e.g., mannitol, sorbitol, lactose), and then freeze-dried. In the aforementioned o/w method, the microspheric preparation may be prepared by a method involving the dispersion of the compound represented by formula (I) in a solvent of an in vivo degradable polymer in an organic solvent, optionally in combination with other pharmaceutical preparations, i.e., s/o/w method.

-   (2) In order to prepare the microspheric preparation by the spray     drying method, an organic solvent or emulsion having the in vivo     degradable polymer and the compound represented by formula (I),     optionally in combination with other pharmaceutical preparations,     dissolved therein is sprayed into the drying chamber of a spray     dryer (spray dryer) through a nozzle so that the organic solvent or     water in the atomized droplets is evaporated in an extremely short     period of time to prepare a microspheric preparation. Examples of     the nozzle employable herein include two liquid nozzle, pressure     nozzle, and rotary disc. It is useful to spray an organic solvent or     an aqueous solution of an aggregation inhibitor (e.g., mannitol,     lactose, gelatin) at the same time with the spray of o/w emulsion as     necessary for the purpose of inhibiting the aggregation of     microspheres. The microspheric preparation thus obtained is then put     under reduced pressure optionally under heating to remove water and     solvent therefrom.

Examples of the film-like preparation include film-like material obtained by dissolving the aforementioned in vivo degradable polymer and compound represented by formula (I), optionally in combination with other pharmaceutical preparations, in an organic solvent, and then subjecting the solution to evaporation to dryness and gelled material obtained by dissolving the aforementioned in vivo degradable polymer and compound represented by formula (I), optionally in combination with other pharmaceutical preparations, in a proper solvent, and then adding a granulating agent (e.g., cellulose, polycarbonate) to the solution.

The microsphere, microcapsule and nanosphere of the present invention may be used as they are. Alternatively, a spherical, rod-like, acicular, pelletized, film-like or cream-like pharmaceutical composition may be processed as a starting material to provide preparations in various forms.

Furthermore, this preparation may be used as a parenteral for local administration (e.g., injection, solid agent such as embedding agent, pellet and powder, liquid agent such as suspension, ointment, etc. to be administered to intramuscular, subcutaneous, organic or articular site). For example, in order to make an injection from the microspheric preparation, the microspheric preparation is suspended with a dispersant, a preservative, an isotonic agent, a buffer, a pH adjustor, etc. to make an aqueous suspension as a practical preparation for injection. Alternatively, the microspheric preparation may be dispersed with a vegetable oil optionally in admixture with a phospholipid such as lecitine or with a middle-chain aliphatic acid triglyceride (e.g., Mygliol-812) to make an oil suspension as an injection which can be practically used.

The particle diameter of the microspheric preparation may be arbitrary so far as it suffices the desired dispersibility and passage through syringe if the preparation is used as a suspension for injection. By way of example, the average particle diameter of the microspheric preparation is from about 0.1 to 300 μm, preferably from about 1 to 150 μm, more preferably from about 2 to 100 μm. The pharmaceutical composition of the invention is preferably in the form of suspension as mentioned above. The pharmaceutical composition of the invention is also preferably in particulate form. This is because the pharmaceutical composition gives less excessive pain to patients when administered through a syringe for use in ordinary hypodermic or intramuscular injection. It is particularly preferred that the pharmaceutical composition of the invention be in the form of injection. Examples of the method for rendering the microspheric preparation aseptic include method which is aseptic throughout the entire steps, method involving sterilization by gamma rays, and method involving the addition of preservative. However, the invention is not limited to these methods.

The pharmaceutical composition of the invention can be used for the treatment of bone diseases in which the amount of bone is decreased because the compound represented by formula (I), optionally in combination with other pharmaceutical preparations, can be gradually released normally for 1 week to 3 months, though depending on the kind and added amount of the in vivo degradable polymer. Among these bone disease treatments, the treatment of fracture often requires that the affected part be fixed and covered with a plaster bandage and the administration of pharmaceutical preparations be conducted only once rather than frequently. Accordingly, the pharmaceutical preparations thus administered are required to accelerate treatment continuously. Thus, the pharmaceutical composition of the invention is useful particularly in this treatment.

The dose of the pharmaceutical composition of the present invention depends on the kind, content and form of the compound represented by formula (I), optionally in combination with other pharmaceutical preparations, the duration of release of pharmaceutical preparations, the animal to be administered, etc., but may be the effective amount of the compound represented by formula (I), optionally in combination with other pharmaceutical preparations. When administered to fracture as a microspheric preparation, for example, one time dose for adult (weight: 50 kg) is from about 0.001 mg to 500 mg, preferably from about 0.01 mg to 50 mg as calculated in terms of effective component. The pharmaceutical composition of the invention may be administered once 1 week to 3 months in the aforementioned amount.
